Annemarie FIRE-ESCAPE.

. Specification of Letters Patent.

Patented July 17, rear.

Application filed. May 29, 1916. Serial No. 100,640.

To all whom it may concern:

Be it known that 1, Mrs. HULDA E. As'rA- RITA, a citizen of the UnitedStates, residing at Brooklyn, in the county of Kings, State of New York,have invented certain new and useful Improvements in Automatic FireEscapes; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to an automatic fire escape.

An object of the invention resides in the provision of an improved fireescape which may be permanently located adjacent to a window so thatportions thereof may be swung out of the window when it is necessary touse the device.

A further object of the invention resides in the provision of a novelcarrier for the persons.

With these and other objects in view, such as will appear as mydescription progresses,

my invention comprises the combination and arrangement of parts as setforth in and falling within the scope of the appended claim.

In the drawing:

Figure 1 is a side elevation of a device constructed in accordance withmy invention showing the pulley supporting arms extended beyond thewindow sill in full lines and in their retracted positions in dottedlines;

Fig. 2 is a plan view;

Fig. 3 is a detail of the shock absorber;

Fig. 4L is a perspective view of one of the carriers, and

Fig. 5 is a sectional view of the same showing the body engaging loop.

The embodiment of my invention illustrated in the drawing includes aframe 1 which is adapted to be secured in a room adjacent to the windowsill 2 and on which a pair of arms 3 is pivoted. Pivoted, at 4, to thesearms 3 are arms 5 on the ends of which pulleys 6 are mounted. These arms3 and 5 are adapted to swing into the positions disclosed in dottedlines in Fig. 1 when the device is not in use and also into thepositions shown in full lines in this figure when the device is in useso that the arms 55 will rest upon the window sill 2. A drum &7 ismounted on the frame 1 and is provided with sprockets 8 over whichchains 9 pass,

which chains pass over additional sprockets 10 and retard the movementof the drum 7. Angularly disposed pulleys 11 are mounted upon this frame1 adjacent to the window sill. A flexible cable 12 passes about the drum7 over the pulleys 11 through guides 13 011 the arms 5 and over thepulleys 6, from which pulleys the ends depend.

Secured to each end of this cable is a carrier which includes a bar 1afrom the ends of which ropes 15 depend. A foot piece 16 is secured tothe ends of these ropes and a seat 17 is likewise secured to the ropesin spaced relation to the foot piece. Eyes 18 are carried by the ropesabove the seat 17 and a fastening member 19 passes through the footpiece 16 and thence upwardly through the seat 17 and through one of theeyes 18, it thence passes to and through the other eye 18 and thenceback through the first eye and through the second eye again and is thenextended downwardly through the seat 17 and the foot piece 16. Thus aloop 19 is formed between the eyes 18. It is obviouswith this carrierthat a number of persons may be carried to the ground by resting uponthe seat and foot piece. Should it be desired to secure the personwithin the carrier it will only be necessary to expand the loop 19 atwhich time the foot piece 16 will be drawn toward the seat 17. The loopmay then be placed around the body of the person who seats himself uponthe seat 17 and rests his feet upon the foot piece 16.

Any pressure exerted against the foot piece will tighten the loop aboutthe body of the person and thus securely fasten him in position.

Secured to the end of each of the arms 5 is a plate 20 on which a secondplate 21 is mounted which is held in spaced relation to the plate 20 bysprings 22. These plates 20 and 21 are provided with central openingsthrough which the cable 12 passes. The presence of the springs betweenthese plates will prevent the sudden stopping of the carriers so thattheir movement toward the pulleys 6 will be arrested gradually.

It will beobvious that the carriers will alternately move to and awayfrom the ground and that the particular arrangement of the drum andsprockets will retard the movement to such an extent that the descentmay be made at a convenient rate of speed.

While I have illustrated and described a rel ing adapted to be swung toan inoperative position interiorly of the window sill and also swing toan operative position with said other arms resting upon said sill, adrum on said frame, pulleys on said other arms, an'gularly disposedpulleys mounted on the pivotal connection between said frame 20 and thefirst named arms, a cable passing over said frame and said pulleys, andearriers secured to the ends of sald cable.

In testimony whereof, I afiix my signature, in the presence of twowitnesses.
